Big Bang Theory star Simon Helberg stepped out in L.A. Thursday, showing off his latest, greatest project to date: his first child with his love of nearly a decade, Jocelyn Towne.

Helberg's wife gave birth to the couple's daughter, Adeline, May 8.

"The family is thrilled," a source told Us Weekly of the proud new parents at the time, adding that Helberg, 31, channeled his Big Bang Theory character prior to welcoming Adeline -- by doing lots of research.

"Simon is excited to be a father," the source shared. "He's been doing his reading!"

The Let Go actor met Towne in Los Angeles; they dated for several years before making it official in a 2007 ceremony. Currently, they reside in Charlie Sheen's former Hollywood estate, which they purchased from the actor for $3 million last November.

上周四，31歲的《生活大爆炸》（Big Bang Theory ）男星西蒙·赫爾伯格（Simon Helberg）攜相愛近10年的妻子喬思林·唐恩（Jocelyn Towne）和他的“最新成果”寶貝女兒一同出行。

可愛的小寶貝艾德林（Adeline）于5月8日降生，是這對夫妻的第一個孩子。

據(jù)知情人士透露，他們小兩口開心極了。就同經(jīng)常做實驗的霍華德一樣，西蒙為迎接女兒也做了很多研究工作。

“升級做爸爸讓西蒙特別激動。他看了好多相關(guān)書籍呢！”

西蒙和喬恩林在洛杉磯相遇，相戀多年后于2007年正式結(jié)婚。去年11月，這對夫婦在好萊塢購下原查理·辛（Charlie Sheen）所有的房產(chǎn)，花費三百萬美金。現(xiàn)在他們一家三口幸福的生活在這里。
